Component Description
A/C unit assembly : Thermo Control Amp.
• Thermo control amp. is composed of thermistor and amplifier. Thermistor is installed on evaporator, and amplifier is attached to foot duct.
• When the thermistor detecting temperature of the evaporator fin is extremely low, thermo control amp. sends the thermo control amp. OFF signal to BCM, and stops the compressor.
A/C unit assembly : Blower Motor
• The blower motor utilizes a brush-less motor with a rotating magnet.
• Quietness is improved over previous motors where the brush was the point of contact and the coil rotated.
A/C unit assembly : Blower Fan Resistor
• Compact and lightweight resistor is adopted with outstanding ventilation.
• Temperature fuse is installed to protects the blower motor circuit.
A/C Control
Controls the air conditioning function.
BCM
BCM transmits A/C ON signal and blower fan ON signal to ECM via CAN communication, according to A/C switch signal and blower fan ON signal that are received from A/C control and thermo control amp. signal that is received from thermo control amp. and A/C indicator is turned ON.
ECM
ECM, when receiving A/C ON signal and blower fan ON signal from BCM, transmits A/C compressor request signal to IPDM E/R via CAN communication according to status of the engine and refrigerant pressure.
IPDM E/R
A/C relay is integrated in IPDM E/R. IPDM E/R operates A/C relay when A/C compressor request signal is received from ECM via CAN communication line.
Refrigerant Pressure Sensor
DESCRIPTION
• The refrigerant pressure sensor converts high-pressure side refrigerant pressure into voltage and outputs it to ECM.
• ECM operates cooling system protection and idle speed control according to voltage value that is input.
STRUCTURE AND OPERATION
• The refrigerant pressure sensor is a capacitance type sensor. It consists of a pressure detection ares and a signal processing area.
• The pressure detection area, which is a variable capacity condenser, changes internal static capacitance according to pressure force.
• The signal processing area detects the static capacitance of the pressure detection area, converts the static capacitance into a voltage value, and transmits the voltage value to ECM.
Magnet Clutch
Compressor is driven by the magnet clutch which is magnetized by electric power supply.

Manual Transmission (MT)
The ignition switch includes a device that helps prevent accidental removal of
the key while driving.
The key can only be removed when the ignition switch is in the LOCK position.
To turn the ignition switch to the LOCK position from the ACC or ON position,
turn the key to the OFF position, ...
